- To all whom Z mug/.concern f Be it known that l', JOHN F. OCoNNon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Draft-Rigging' for Railway-Cars, of which the following is a ful-l, clear, concise, and exact description,`

reference being. had to the a'companyi'ng drawings, forming a part. of this specification.

My invention relates to improvements in draftv rigging for railway cars.

The objectot1 my invention is to provide a draft rigging of simple and cheap Aconstruction, and one of simple operation.

In the drawings forming a 'part of this specificationV Figure 1 isa side elevation partly in longitudinal section on line 1-1 of Fig. 2 of a. draft rigging embodying my invention. F ig. 2 .is a plan View partly in horizontal longitudinal section on, line 2-2 of lfig. 1. Fig. 3 is a. side elevation partly in vertical longitudinal section showing the position of the parts in full compression on pulling movement of the draftl rigging. Fig. 1 is a side elevation partlyi vertical longitudinal section showing the position of theparts under full compression in hutiin'g movement ofhe draft Fig. 5 isa half crosssectionon line -Qof Fig. 1. Fig. 6 is a half cross section on line 6e-6 of Fig. 1. Fig. 7 is Va perspective view of the Wedge housing. Fi g. 8 is a perspective vieW of the Wedge. Fig. 9 is a perspective view of the friction blocks. f

Referring tothedrawings 1 0, 10 represent dra-ft sills, 'Orfparts of the car frame to which the draft rigging isy applied, 11 the end sill, 12 ythe buii'er block, 13 the draw-bar carry iron, 14, 14 stop members .i suitably secwaredlto the draft Amembers and in opposednijelatobetween the same, said stop members being"provided with front stop shoulders v15, 16, rear limiting stop shoulders 16, 16,'rear limiting stop shoulders 17, 17, and rear .stop shoulders 13, 18. The foregoing parts are of Weil known construct-ion.

19, 19 represent guide plates secured to the under faces of the stop members 14.-. 14. preferably by bolts 20, 20, and adapted to supportthe transversely arranged front aud Boi tvveen the followers are located the. friction i slot l2 oi' the wedge when the p'arts of the 11o rear followers 21 and 22. respectively.

members 23 ot' the draft gear, the s 'ng mechanism 2d of' the draft gear mounted back of the rear follower 22. The rearffollower 22 is provided with a pair ot' forwardly. extended limbs 25, 25 pass ing either side of thetriction members 23 jot the 'draft gear, and forming with the rear follower a loop or draft yoke. The limbs 25, 25 are provided near their tor- W'ard 'ends with 'lateral slots 26 to. the coupler key 27. The coupler keynef-weee through the transverseslot 28 in the drawbar 29, and also in'preferabie construction through slots 30, 30 iii-the 'draft members. 'The siots 30, 30 in the dratt members and the slots 26, 26 in the limbs 25, 2o ,are longitudinally extended to permitJ the engagement. of the butt 'of the draw-bar with the front follower 21 'n bung increment of the vdraft rigging without strain upon the key 27. y

The friction members 23 'of thedrat gear comprise a housing 31, a Ltvedgi-i 32, and friction blocks 33, 33. The housin guiar' in 'cross section, and open at its forward end' 34 and its rearward 'end 35. Across the forward opening said box-litre member is provided with a oar 36, preer ably integral with said box-like animalier..

si is a hollow box-like member, preterab y restanthe .said bar 36 is provided. rIhe upper and lower plates 89 and 40 respectively of til-.e hollow box-like member 'of the housing are provided on their inner faces with angu lar friction faces el, 41; in preferable construction dieangle thereof being substantially thirty degrees tothe plane of the said plates.

The Wedge 32 comprises a block for- Wardly provided with a central slot 42 adapted to slidingly receive the central bar 8G ot' the housing, the legs 43 of said b i turcated wedge forming the sides of the said slots 42 being adapted topass at either side ot the bar 56 ot the housing 31 when'the wedge and housing are in assembled relation. The roar faro 4:1 of the bar 3G iS adapted to engage the rear end 45 of the y the housing 81 and wedge 32 is interposed a friction block 33, the said friction blocks being preferably three sided or triangular in cross section, and provided with friction faces 49, 49, 49, oneof said friction faces engaging with a friction face of the wedge, and' another friction face engaging with a friction face of the housing The other friction face of each friction block is adapt-. ed to engage the front face 51 of the rear follower 22.

The wedge 32 is provided at its rear end with a flat surface 52, which is adapted to engage' the lfront face 51 of the rear follower in full compression of the parts in buiiing and draft movements of the gear. The wedge is provided with a longitudinal o ening 53 registering with the opening 3 in the bar BGof the housing. f

The friction blocks 33 at their 4meeting edges are each provided lwith ay groove 54,

Y the said grooves when the friction blocks are in normal position7 as illustrated in Fig. 'l

of the drawings, forming an opening registering with'the opening 53 in the wedge 32. A spring bolt 55 -passestlirough the openings 37 in the housing, 53 in the wedge, and the said grooves in the friction block, and through a perforation 5.6 through the 'rear follower 22,- and is rearwardly extended from the said rear 'follower a suitable distance to permit the mounting about the same of the spring members 24. The spring bolt 55 is forwardly provided with a head 57, and is rearwardly provided with the nut..58.

The spring members 24 preferably com prisc an inner 'spring 59 and an outer spring 60, the said springs being forwardly seated against the rear face G1 of the follower 22,`

and rearward] y seated against the frontface 62 of the spring seat 63, which is maintained in position upon the said spring bolt by the nut 58.. i

The frontv follower 21 is provided at either lateral edge with a notch 64 for the passage of the Vlimbs 25, 25 of the yoke member.

On rear'ward movement of the draw-bar -the front follower 21 moves rearwardly. The said front follower through its engage-` ment with the forward ends of the legs 43 of 4 the stop shoulders 18. blocks moves upwardly and the other down--v` the wedge 32 moves said wedge rearwardly. 'lhe rear follower 22 isfstatinary against One of the friction;`

Idraw-bar. i y y 2. In a draft :rigging for railway cars, the `combination with draft members, of parts `mounted between the draft members comwardly, the said blocks being forced trans- "versely away from each other by the rea-r- `ward movementof the wedge, the said blocks each being in frictional engagementv'ith a wedging face ofthe wedge, a wedgjiiig face of the housing andavith the for-y fward face of the rear follower. -nieiit of the wedges away from'each other lforces the housing forwardly through the ,5 engagement between the friction blocks and "..the friction faces of the housing. The for- 4 The moveward movement o-fI the housing draws the =spring bolt forwardly, thus compressing the spring members between the rear face 61 of fthe rear fol/lower 22 and the spring seat 63. 'This movement of the parts continues until the rear face 52 of thewedge 32 engages the :front face 51 of the rear follower 22. The gposition of the parts when in full compression in buliing movement is illustrated by IFig. 4'of the drawings. In forward move-V ment of thel draw-bar the front follower 21 1is stationary aga-inst the front stop shoulders I15, 15, the wedge 32 through its limbs 43, 43 `engages the front follower and is stationary, the rear follower is drawn forwardly, and -the friction blocks move outwardly and for-l wardly'in frictional engagement with the4 vfriction faces of the housing, the friction, faces of the. wedge and the forward face of;

the rear follower, and in suoli forward and outward movement the housing is moved forwardly, drawing the spring bolt forfwardly,.and'compressing the spring members 24 between the spring seat 63 and the rear face 61 yof the'forwardly moving rear follower 22.
